Connecting Streaming to Plus

In the living room I have a 2tb hard drive connected to a WDTV Live Plus and that is connected to my wifi router. It is working properly because I can watch media from my laptop and iPhone. In the theater room I have a WDTV Live Streaming connected to my wifi network. I’m having a problem getting it to recognize the WDTV in the living room. What can I do?

Make sure they’re all on the same workgroup.

Dumb question, but does that mean just naming it “WORKGROUP”?  If that’s the case then they are.

Fixed it.  I put the wrong ip address in.
